The army said a rocket alert siren that was activated in southern Israel on Monday morning was a false alarm.

The siren went off in the Ein Hashlosha and Nirim communities, near the Gaza Strip, according to the IDF’s Home Front Command.

The army did not say why the alarm was triggered.

There were no immediate reports of a rocket striking Israeli territory or of explosions heard in the area. After a few tense minutes, the army determined that it had not detected rocket fire coming from the Gaza Strip.

In December, a rocket alert siren sounded in southern Israel, near the Sinai Peninsula. No rocket struck Israeli territory, though it seems two projectiles were indeed fired at the Jewish state by an Islamic State affiliate in Sinai.
